Subject: Re: [grouper-users] Error when i want to view all inherited privileges in registry

Hi,
i did some debug.
I think, it comes from findPrivilegeInheritRules and findSubjectPrivilegeInheritRules methods in RuleFinder class
For example, in findPrivilegeInheritRules method at line 91, if we have thenEl instead of thenEnum, ruleDefinition.getThen().thenEnum() return null.
Switch statement doesn't support a null case, i think that's why i have the error below.

Hope it can help,
thanks,
Yoann.
